An effort to honor little bluestem as the state grass of Kansas has taken root among legislators. On a voice vote, the Kansas House gave first-round approval Wednesday to a bill bestowing the honor. Approval on a final vote, expected Thursday, would send the measure to the Senate. Students from Shawnee Mission South High School in Overland Park ave pushed the idea. The House rejected amendments to confer the honor on big bluestem, dominant in the eastern part of the state, and buffalo grass, dominant in western Kansas. Republican Rep. Sharon Schwartz, of Washington, said little bluestem is "a compromise species" found in every Kansas county.
